What Is Cold Cranking Amps (CCA) & Why It Matters in Canada

Just Imagine: it's -25°C in Winnipeg on a January morning. You're already running late. You turn the key, and your car just… clicks. That dreaded sound is often caused by one thing - a battery without enough Cold Cranking Amps (CCA).

Understanding Cold Cranking Amps (CCA) is one of the most important things any Canadian driver can do before winter arrives. It is not just a technical number on a battery label. It is the difference between getting to work on time and being stranded in a freezing driveway.

In this complete guide, we break down exactly what CCA means, why it matters in Canada specifically, and how to choose the right battery for your vehicle and climate.

What Is Cold Cranking Amps (CCA)?

Cold Cranking Amps (CCA) is a measure of a battery's ability to start an engine in cold temperatures. Specifically, CCA indicates the number of amps a battery delivers at 0°F (-17.8°C) for 30 seconds while maintaining a voltage of at least 7.2 volts.

In simple terms, CCA tells you how powerful your battery is when the temperature drops. The higher the number, the stronger the starting punch your battery delivers on a freezing morning.

Every car battery you buy in Canada will have a CCA rating printed on the label. This number is one of the most important specifications to check, especially if you live in provinces like Alberta, Manitoba, Saskatchewan, or Ontario, where temperatures regularly fall well below freezing.

How Is CCA Measured?

Battery manufacturers test CCA under controlled laboratory conditions. Batteries go through rigorous factory tests in extreme temperatures to achieve their CCA rating. The higher the CCA rating, the greater the starting power of the battery.

The test works like this: a fully charged 12-volt battery is placed at exactly 0°F (-17.8°C). It must then deliver a specific number of amps continuously for 30 seconds without dropping below 7.2 volts. If it passes, the battery earns that CCA rating. This process ensures the number you see on the label reflects real-world cold-weather performance.

How Does Cold Weather Affect Your Car Battery?

Your car battery generates power through internal chemical reactions. However, cold weather slows those reactions significantly. When temperatures drop, battery chemicals slow down, reducing current output. Engine oil also thickens, making the engine harder to turn over. In diesel engines, fuel may gel, creating even more resistance.

The result is a double problem: your battery produces less power right when your engine needs more of it. When the mercury takes a dive below zero, car batteries lose about 60 per cent of their power, but car engines need up to double the power to start in freezing weather.

That is exactly why CCA exists as a rating. It gives you a reliable standard to compare batteries and choose one capable of handling Canadian winters.

Why Cold Cranking Amps (CCA) Matter More in Canada

Canada is one of the coldest countries in the world for daily drivers. Cities like Edmonton, Saskatoon, Thunder Bay, and Whitehorse regularly see temperatures drop to -30°C and below. That is not a mild inconvenience for your battery - it is an extreme stress test happening every single morning.

For vehicles operated in lower temperatures, it is harder for your engine to turn over in cold weather. A higher CCA rating means the battery can provide more power to the starter motor, turning the engine over faster and more reliably in extreme conditions. Without enough CCA, even the most advanced vehicles can struggle to start.

Canadian drivers also tend to make more short trips during winter. Short trips do not give the alternator enough time to fully recharge the battery. Therefore, the battery starts each cold morning slightly less charged than the day before, which makes having a sufficient CCA rating even more critical.

Vehicle manufacturers spend hundreds of hours working with engineers to determine the appropriate CCA levels for each make and model in a variety of climates. However, those OEM recommendations are often set for average conditions. In Canada, it almost always pays to meet or slightly exceed the manufacturer's recommendation.

CCA vs. CA (Cranking Amps): What's the Difference?

When shopping for a battery, you will likely see two ratings: CCA and CA. These sound similar but measure very different things.

Cranking Amps (CA) and Cold Cranking Amps (CCA) measure a car battery's power delivery in different conditions. CA gauges power at 32°F (0°C) for general starting in moderate climates, while CCA evaluates power at 0°F (-17.8°C).

Because CA is tested at a warmer temperature, it is always a higher number than CCA for the same battery. This distinction matters because some battery labels prominently display the CA rating, which can mislead buyers into thinking they are getting more cold-weather power than they actually are.

Important: Buying a CA rating thinking it's CCA can undersize your battery by 20–30%. In cold weather, the engine may crank slowly or not start at all.

For Canadian drivers, always look for the CCA rating. That is the number that actually reflects your battery's performance in the conditions you face every winter.

You may also encounter MCA (Marine Cranking Amps), which is tested at 32°F (0°C) like CA. If your car needs 500 CCA, a 500 MCA battery may fail in winter. You need an MCA about 20–25% higher than your required CCA for the same cold-start performance.

Best Mobility Scooter Batteries for Canadian Weather

If you own a mobility scooter in Canada, you already know how brutal the winters can be. Temperatures in cities like Calgary, Winnipeg, and Toronto regularly drop well below freezing. This kind of cold puts enormous strain on your scooter's power source. Choosing the right mobility scooter batteries is one of the most important decisions you can make as a Canadian rider.

The wrong battery will fail faster, lose range quickly in cold conditions, and leave you stranded at the worst possible time. However, the right battery will keep you moving safely and independently throughout every season. Whether you use a folding mobility scooter for grocery runs, an enclosed mobility scooter for year-round commuting, or a heavy-duty electric mobility scooter for outdoor adventures, your battery is the heart of the machine.

This guide breaks down everything you need to know about mobility scooter batteries in Canada, from the best battery types for cold weather to expert storage and charging tips that will extend your battery's lifespan.

Why Choosing the Right Mobility Scooter Batteries Matters in Canada

Canada's climate is unique. The country experiences some of the most extreme seasonal temperature swings in the world. A battery that works well in a mild climate may not deliver reliable performance on a -20°C February morning in Calgary or during a damp, salt-laden winter in Vancouver.

Your mobility scooter is more than a convenience; it's your independence. A failing battery means reduced range, sluggish performance, and unexpected breakdowns. Also, replacing a low-quality battery more frequently adds up in cost over time. Therefore, investing in a battery suited to Canadian conditions makes financial and practical sense.

Canadians who use enclosed mobility scooters or fully enclosed mobility scooters for year-round travel need batteries that can handle cold starts, moisture exposure, and longer idle periods during snowstorms. Those who rent out mobility scooters, such as mobility scooter rental services in Toronto and other cities, also need batteries that withstand heavy, repetitive use in variable weather.

How Canadian Weather Affects Mobility Scooter Batteries

Understanding how cold and moisture affect your battery helps you make smarter choices. Canada's winters are not just cold; they are wet, salty, and prolonged. Each of these factors takes a toll on battery chemistry and performance.

Cold Temperature and Battery Capacity Loss

All batteries, regardless of type, lose efficiency as temperatures drop. The chemical reactions inside a battery cell slow down considerably when temperatures fall below 10°C. Below freezing (0°C), these reactions slow even further, causing a noticeable drop in available capacity.

Research shows that battery capacity can drop by 10% to 20% for every 10°C reduction in temperature. On a very cold Canadian winter day at -20°C, a battery that normally gives you 20 km of range might only deliver 12 to 14 km. This is a critical safety consideration for riders who travel longer distances on their electric mobility scooters.

Canadian Weather Tip: Scooter batteries perform best between 15°C and 25°C. Always bring your scooter indoors during extreme cold whenever possible.

Road Salt, Moisture, and Corrosion Risks

Canadian roads are heavily salted during winter. Salt spray and moisture can work their way into battery terminals, charging ports, and electrical connectors. Over time, this causes corrosion that reduces conductivity and can permanently damage battery components.

If you use your scooter outdoors regularly during winter, clean the battery terminals and connections after every ride. A dry cloth and a dab of dielectric grease on the terminals can prevent costly corrosion damage. This is especially important for folding mobility scooters and used enclosed mobility scooters that may have worn seals or older wiring.

UPS Battery Replacement Guide (Canada)

Power outages are unpredictable - but your response to them doesn't have to be. A UPS (Uninterruptible Power Supply) is the last line of defence for your computers, servers, networking gear, and other critical electronics when the grid fails. But here's the catch: a UPS is only as reliable as the battery inside it. If your battery is aging, degraded, or dead, your UPS is essentially just an expensive extension cord. This complete UPS battery replacement guide is written specifically for Canadian homes and businesses, helping you understand when to replace your battery, how to do it safely, and where to buy the right one.

What Is a UPS Battery and Why Does It Matter?

A UPS system stores electrical energy in an internal battery and releases it instantly when your main power supply fails or fluctuates. Whether you're running a small home office in Calgary, a retail shop in Vancouver, or a server room in Toronto, a functioning UPS battery ensures your equipment shuts down safely or continues running during a blackout, brownout, or power surge.

Without a healthy battery, your UPS cannot fulfil its core purpose. Data can be lost, hardware can be damaged, and critical operations can be interrupted. Think of the UPS battery the same way you'd think of the battery in a smoke detector - you rarely need it until you suddenly need it urgently.

Types of UPS Batteries: VRLA, AGM, and Lithium-Ion Explained

Understanding the type of battery in your UPS system is the first step to replacing it correctly.

VRLA (Valve-Regulated Lead-Acid) batteries are by far the most widely used in UPS systems. They are sealed and maintenance-free, making them relatively cheap and applicable in small to medium-sized UPS configurations. Within the VRLA category, you'll most commonly encounter AGM (Absorbent Glass Mat) batteries. AGM technology integrates thin glass fibres woven into a mat, significantly raising energy density and allowing a faster rate of discharge. These are the go-to choices for most APC, Eaton, CyberPower, and Tripp Lite UPS units sold in Canada.

Lithium-Ion batteries represent the next generation of UPS power. Lithium-ion batteries offer a longer lifespan, often lasting between 8 to 12 years, with higher energy density and a longer cycle life compared to SLA batteries. They are lighter, handle heat better, and require far less maintenance - making them an excellent long-term investment for businesses and data centres, though they come at a higher upfront cost.

For most Canadian homeowners and small businesses, replacing a standard UPS with a high-quality VRLA/AGM battery is the practical and cost-effective choice.

6V vs 8V vs 12V Golf Cart Batteries: Which Is Best?

Whether you're cruising the fairways of a golf course or navigating a large property, your golf cart is only as reliable as the battery powering it. One of the most common questions Canadian golf cart owners ask is: Should I choose a 6V, 8V, or 12V battery? It's not just a matter of voltage - the choice directly affects your cart's range, speed, hill-climbing ability, maintenance demands, and overall cost of ownership.

At Batteries Store, we carry all three voltage options - 6V, 8V, and 12V golf cart batteries - and this guide is here to help you make a fully informed decision before you buy.

Understanding Golf Cart Battery Voltage Systems (36V vs 48V)

Before diving into the individual battery types, it's important to understand how golf cart electrical systems work. Golf carts typically operate at either 36V or 48V total system voltage, achieved by connecting multiple individual batteries in series. The voltage of each battery determines how many you need to reach that system total.

For a 48V system, you would need eight 6V batteries, six 8V batteries, or four 12V batteries. For a 36V system, you'd use six 6V batteries or three 12V batteries. Determining the correct voltage system for your golf cart is crucial to ensure accurate battery selection. Always check your cart's specifications before purchasing.

6V Golf Cart Batteries: Deep Cycle Power and Longevity

The 6V battery is the time-tested classic of the golf cart world. These are the most common in older or more traditional golf carts, and are typically connected in series to form either a 36V system using six batteries or a 48V system using eight batteries.

What makes the 6V stand out is its deep-cycle design. They are proven deep-cycle workhorses with thick plates that handle repeated discharge and recharge without quick degradation, and they offer stable voltage under steady load, which helps maintain consistent torque and smoother acceleration. This is particularly useful on hilly terrain or courses with uneven ground.

6V batteries are known for their durability and ability to handle deep discharge cycles, making them suitable for heavy-duty use. Think of a cart used for an all-day tournament - the 6V battery pack is built to keep going without a dramatic drop in performance.

The tradeoff is complexity. Eight batteries mean eight connections, eight terminals, and more overall maintenance. Flooded 6V lead-acid units require watering, terminal cleaning, and regular equalization, and neglect accelerates sulfation and shortens the lifecycle. That said, for serious golfers or fleet operators who prioritize longevity over convenience, the 6V remains a top choice.

What Does Battery Group Size Mean? Complete Guide

If you have ever walked into a battery store and stared blankly at rows of batteries, wondering which one fits your car, boat, or RV, you are not alone. One of the most confusing aspects of buying a battery is understanding what the group size means and why it matters. Whether you are searching for a car battery group size chart, a marine battery group size chart, or a 12V battery group size chart, this complete guide will walk you through everything you need to know.

At Batteries Store, we help customers find the right battery every single day. This guide is designed to take the guesswork out of the process so you can shop with confidence, extend your battery life, and keep your vehicle or equipment running at its best.

What Is Battery Group Size?

Battery group size is a standardized code assigned by the Battery Council International (BCI) that defines the physical dimensions of a battery - specifically its length, width, and height - along with the placement of its terminals (positive and negative posts). It is not a measurement of power output, voltage, or brand. It is purely a sizing and fitment standard.

Think of battery group size the way you think of shoe size. A size 10 shoe does not tell you how comfortable it is, what colour it comes in, or how long it will last - it simply tells you the shape and fit. Similarly, a battery group size like Group 24, Group 35, or Group 65 tells you the physical box dimensions and terminal layout, ensuring the battery will physically fit into the battery tray of your vehicle and that the cables will reach the correct terminals.

Group sizes are typically expressed as a two-digit number (e.g., 24, 35, 51, 65, 75, 78) or a number-letter combination (e.g., 24F, 34R, 51R). The letter suffix indicates terminal placement - for example, "F" means the positive terminal is on the right side when facing the battery, while "R" indicates it is reversed.

Why Does Battery Group Size Matter?

Choosing the wrong battery group size can lead to a surprising range of problems. Here is why getting the right group size is so important:

Physical Fit: A battery that is too large will not fit in the battery tray or under the hood. A battery that is too small may shift around during driving, causing vibration damage to both the battery and the vehicle.

Terminal Placement: If the positive and negative terminals are in the wrong positions, the cables may not reach or may be forced into unnatural positions, creating short-circuit risks.

Secure Mounting: Batteries are held in place with hold-down brackets. An incorrectly sized battery may not be properly secured, leading to vibration damage and potentially dangerous battery acid spills.

Electrical Compatibility: The battery must fit within the vehicle's battery management and charging system. Installing the wrong group size can affect the electrical system's ability to maintain a proper charge.

In short, the battery group size is the first filter you should apply when shopping for any replacement battery - before you even look at Cold Cranking Amps (CCA), Reserve Capacity (RC), or brand.

Deep Cycle Batteries Explained: Uses and Benefits

When it comes to reliable, long-lasting power, not all batteries are built the same. If you are running an RV, boat, solar system, or backup power setup, you have likely come across the term deep cycle battery. Many people ask, “What is a deep cycle battery, and how is it different from a regular battery?”

Let’s understand deep cycle batteries in detail, how they work, where they are used, and how to choose the right one for your needs in Canada.

What Is a Deep Cycle Battery?

A deep cycle battery is designed to provide steady power over a long period of time and to be repeatedly discharged and recharged without damage. Unlike car starting batteries, which deliver a short burst of energy to start an engine, deep cycle batteries are built to supply continuous power at a consistent level.

This ability to handle deep discharges is what makes them ideal for applications like RVs, marine systems, solar power, and backup energy storage. When people search for what is a deep cycle battery, they are usually looking for a battery that can run equipment, lights, appliances, or electronics for hours rather than seconds.

How Deep Cycle Batteries Work Compared to Regular Batteries

The internal design of a deep cycle battery is what sets it apart. It uses thicker plates and denser active material, allowing it to be discharged to a much lower level and then recharged repeatedly.

A typical car battery is damaged if it is deeply discharged too often. A deep cycle battery, on the other hand, is designed for this exact purpose. This makes it far more suitable for systems that draw power continuously, such as RV electrical systems, marine electronics, and off-grid solar setups.

Smoke Alarm Chirping at Night? Battery Fix Explained

Few things are more frustrating than a smoke alarm chirping in the middle of the night. The house is quiet, everyone is asleep, and suddenly a sharp, high-pitched beep breaks the silence. Many Canadian homeowners experience this issue, especially during colder months, and immediately wonder, “Why is my smoke alarm chirping at night?”

In most cases, the answer comes down to one simple cause: the battery. However, understanding why smoke alarms beep more at night, how to stop the chirping properly, and when a battery replacement is enough can help you fix the problem quickly and keep your home safe.

Let’s understand everything you need to know, from low-battery behavior to proper testing and long-term prevention.

Why Is My Smoke Alarm Chirping at Night?

A chirping smoke alarm is designed to alert you to a problem, not a fire. Unlike a continuous alarm sound, a single beep every 30 to 60 seconds usually indicates a battery or maintenance issue.

Nighttime chirping happens more often because smoke alarms are extremely sensitive to voltage changes. During the night, indoor temperatures tend to drop, especially in Canadian homes during fall and winter. When temperatures fall, battery voltage drops slightly as well. If the battery is already weak, this small drop is enough to trigger the low-battery warning.

Another reason people notice chirping more at night is the silence. Background noise during the day masks the sound, but at night, even one beep feels loud and persistent.

Car Battery Dies Overnight in Cold Weather? Guide for Canadian Drivers

If your car battery dies overnight in cold weather, you’re not alone. Canadian winters, especially in cities like Calgary, create some of the harshest driving conditions in North America. Temperatures often plunge to –25°C, –30°C or even lower. The cold slows battery chemistry, thickens engine oil, increases electrical resistance and turns a healthy battery into a dead one the next morning.

Whether your vehicle is parked outside, used only for short trips or running an older battery, cold weather can expose every weakness. This guide explains exactly why car batteries die overnight, how to recognize early failure signs, how to protect your battery in freezing conditions, and which winter-ready batteries perform best in Canada.

Why Car Batteries Die Overnight in Cold Weather

Car batteries rely on chemical reactions to generate electricity, and those reactions slow dramatically in freezing temperatures. At –18°C a battery may deliver only half of its normal power. Meanwhile, the engine requires nearly double the power to start because the oil becomes thicker.

When your battery has reduced power and your engine needs more power at the same time, a no-start situation becomes very likely.

What cold weather does to your battery:

It slows internal chemical activity

It thickens engine oil and makes the starter work harder

It increases electrical load from heaters, lights and defrosters

It reduces the battery’s ability to recharge fully

It increases the freezing risk of partially charged batteries

A fully charged battery freezes around –55°C, but a low-charge battery can freeze near –15°C - temperatures Calgary regularly experiences in winter.

Free Battery Testing in Calgary: Know If Your Car Battery Is Dead

A dead car battery on a freezing Calgary morning is one of the most frustrating experiences for any driver. Cold temperatures reduce battery power, thicken engine oil and increase the load on your electrical system. These factors make winter the most common season for sudden battery failures. Getting a free battery test in Calgary is the easiest way to know if your battery is weak, dying or completely dead before it leaves you stranded.

Let's understand why battery testing is important, how it works, when to get it checked and where to go in Calgary for fast and affordable battery replacement.

Free Battery Testing in Calgary: Why It Matters Before Your Battery Dies

Most drivers assume their battery is fine until the car refuses to start. In reality, a battery can lose performance long before it fails. A professional test helps you understand the actual condition of your battery so you can take action at the right time.

A free test provides information about your battery’s ability to hold a charge, deliver starting power and perform properly in extreme cold. This becomes especially important in Calgary’s long winter season when low temperatures can drop battery capacity by half.

Common Signs Your Car Battery Is Dead or Dying

Many batteries show warning signs that most drivers overlook until it is too late. These signs include slow engine cranking, clicking sounds when turning the key, dim interior or exterior lights, dashboard warning lights, electrical features resetting or a burning smell caused by internal battery issues.

If any of these symptoms appear, you should get your battery tested immediately. Early diagnosis prevents unexpected breakdowns.

4D vs 8D Battery Comparison: Size, Capacity, Power and Uses

Choosing the right heavy-duty battery is not just about fitment—it’s about reliability, power, and cold-weather performance, especially in a city like Calgary, where winter temperatures can drop well below freezing.

If you’re comparing 4D vs 8D batteries, this guide will help you understand the size differences, power output, real-world uses, and which battery performs better during harsh Canadian winters.

Whether you operate a commercial truck, construction equipment, RV, marine vessel, or backup generator, making the right choice can save you from cold-start failures and costly downtime.

What Is a 4D Battery?

A 4D battery is a large commercial battery designed to deliver dependable starting power for medium-duty vehicles and equipment. It offers a balance between physical size, power output, and cost, making it a common choice across many commercial applications. In terms of specifications, a typical 4D battery delivers around 160–200 amp-hours of capacity and produces approximately 1,000–1,200 cold cranking amps (CCA). This level of power is sufficient for many diesel engines, provided the battery is well maintained and properly matched to the vehicle’s electrical load.

4D batteries are commonly used in delivery trucks, construction equipment, backup generators, and RVs where space is limited. In Calgary winters, they can perform reliably when vehicles are driven regularly and electrical loads are kept under control.

What Is an 8D Battery?

An 8D battery is the largest standard battery size used in heavy-duty and industrial applications. It is built for maximum power output and extended reserve capacity, making it a preferred choice for vehicles that operate in extreme environments.

Most 8D batteries offer 225–255 amp-hours of capacity and 1,400–1,600 CCA, giving them a significant advantage during cold starts. The larger internal plates and higher electrolyte volume allow 8D batteries to maintain voltage stability even in sub-zero temperatures.

In Calgary, 8D batteries are commonly installed in semi-trucks, snowplows, oilfield equipment, marine vessels, and large RVs. Their ability to handle high electrical demand makes them particularly valuable during long winter idling and overnight cold exposure.

Engine Cranks but Won’t Start in Cold Weather — Most Common Causes

Few things are more frustrating than turning the key on a freezing Calgary morning, hearing the engine crank, and then… nothing. The vehicle sounds like it wants to start, but it just won’t fire up. This problem becomes extremely common during winter, especially when temperatures dip well below zero.

While many drivers assume this is a fuel or engine issue, in most winter cases, the root cause is battery-related. Understanding why this happens can help you avoid unnecessary repairs, prevent breakdowns, and choose the right battery solutions for Calgary’s harsh climate.

Why This Problem Is So Common in Calgary Winters

Cold weather slows down chemical reactions inside your battery while simultaneously increasing the amount of power your engine needs to start. The result is a perfect storm: your battery delivers less power exactly when your vehicle demands more.

In Calgary, overnight temperatures often drop low enough to expose weak batteries that may seem fine during warmer months. That’s why this issue usually appears suddenly during winter rather than gradually.

What Does “Engine Cranks but Won’t Start” Actually Mean?

When your engine cranks, it means the starter motor is turning the engine over. However, starting the engine requires additional electrical power to fuel injection systems, ignition components, and onboard electronics.

In cold weather, a battery may have enough power to crank the engine but not enough usable voltage under load to complete the starting process. This is why the battery is often the main culprit—even when the engine sounds active.

Weak Battery Due to Cold Temperatures

This is the most common cause of winter no-start issues in Calgary. Cold weather can reduce a battery’s effective power output by 30–50 percent, depending on temperature and battery condition.

If your battery is marginal, winter will expose it immediately. Vehicles with older batteries or low Cold Cranking Amps (CCA) are especially vulnerable during cold snaps.

AGM vs Lead-Acid Batteries: Which Performs Better in Cold Weather

When Calgary’s winter hits hard and temperatures dip below freezing, your vehicle’s battery faces its toughest challenge. Cold weather slows the chemical reactions inside a battery, reducing its ability to deliver power when you need it most. That’s why choosing the right battery type—AGM or lead-acid—can make a big difference in performance, reliability, and longevity during those frosty mornings.

So, which battery type is better suited for Calgary’s cold climate? Let’s break down how AGM and lead-acid batteries perform when the mercury drops.

Understanding the Basics

Lead-acid batteries have been around for more than a century. They use liquid electrolyte to produce electrical energy and are known for their affordability and dependable performance. However, they can struggle in extreme cold because the liquid inside can thicken or even freeze, slowing the chemical reaction.

AGM batteries (Absorbent Glass Mat) are a newer, more advanced version of lead-acid batteries. Instead of free-flowing liquid, AGM batteries use fiberglass mats to hold the electrolyte, making them spill-proof, maintenance-free, and more resistant to temperature extremes.

How Cold Weather Affects Battery Performance

Cold weather is a battery’s worst enemy. As temperatures drop, the chemical reactions inside slow down, reducing power output. At -18°C, a typical car battery can lose up to 40% of its capacity, while your engine requires almost twice as much power to start.

This is where battery design and technology matter most. AGM batteries are engineered to perform better in these challenging conditions, making them a popular choice among Canadian drivers who face long winters.

AGM Batteries in Cold Weather

AGM batteries are designed to handle the cold far more efficiently than traditional flooded lead-acid types. Their sealed design minimizes internal resistance, allowing for faster power delivery to the starter motor.

Here’s why they excel in Calgary’s cold weather:

Higher Cold Cranking Amps (CCA): AGM batteries deliver higher CCA ratings, ensuring reliable starts even in sub-zero temperatures.

Better Vibration Resistance: Calgary’s icy roads can cause vibrations that wear out standard batteries faster—AGM’s tightly packed plates prevent that.

Faster Recharge Time: They recharge more quickly, which is useful for short winter drives when alternator output is limited.

Maintenance-Free: There’s no need to top off electrolyte levels, and the sealed design prevents freezing or leakage.

Simply put, AGM batteries are built for performance in harsh winter conditions.

Can I Recharge and Use a Discharged Battery?

Few things are more frustrating than finding your car won’t start — especially on a cold Calgary morning. Most often, the culprit is a discharged battery, leaving many drivers wondering if it can be recharged and used again.

The answer isn’t always black and white. While some discharged batteries can be safely revived with the right charger, others may be too far gone to hold power effectively. Understanding why your battery discharged, how to recharge it properly, and when it’s time for a replacement can save you money and prevent unexpected breakdowns — particularly in Calgary’s tough winter conditions.

Let’s explore how to bring a dead battery back to life — and when to know it’s time for a new one.

What Does a “Discharged Battery” Mean?

A discharged battery simply means the battery has lost its stored electrical energy. This can happen due to:

Leaving headlights or interior lights on

Cold Calgary winters reducing the chemical activity inside the battery

A faulty alternator or parasitic drain

Age-related wear and tear

When your car battery voltage drops below 12.4 volts, it’s considered partially discharged. Anything under 12 volts is deeply discharged and may need proper recharging before it can work again.

Can You Recharge a Discharged Battery?

Yes — most lead-acid and AGM car batteries can be recharged using the right charger. However, the success of recharging depends on how deeply the battery was discharged and how long it stayed that way.

Slightly Discharged Batteries (12.2–12.4 volts):

These can often be revived using a standard battery charger or by taking a longer drive so your vehicle’s alternator can replenish the charge.

Deeply Discharged Batteries (below 12 volts):

These require a smart charger or a trickle charger that can slowly and safely bring the voltage back up without overheating or overcharging.

If the battery remains below 10 volts for an extended period, sulfation (crystal buildup inside the cells) may occur, making it harder to recharge fully.

How Long Do Scissor Lift Batteries Last?

Scissor lifts are essential equipment in construction sites, warehouses, and industrial facilities. To keep them running smoothly, having a reliable battery is crucial. But one of the most common question is How long do scissor lift batteries last?

The answer depends on a variety of factors such as the type of battery, usage patterns, and maintenance practices. Let’s break it down.

Average Lifespan of Scissor Lift Batteries

On average, scissor lift batteries last between 3 to 5 years. However, their actual lifespan can vary:

Light usage with proper maintenance → up to 5 years.

Heavy daily usage → around 2–3 years.

Poorly maintained batteries → may fail within 1–2 years.

In terms of performance, most fully charged scissor lift batteries provide 6–8 hours of continuous use before needing a recharge.

Factors That Affect Battery Life

1. Battery Type

Lead-acid batteries (most common) → lower upfront cost but require regular maintenance.

AGM or Gel batteries → maintenance-free and usually last longer.

2. Usage Frequency

Daily heavy use drains batteries faster compared to occasional light use.

3. Charging Habits

Overcharging or undercharging shortens battery life.

Partial charging can reduce long-term performance.

4. Maintenance

Regular water level checks (for flooded lead-acid batteries).

Keeping batteries clean and corrosion-free.

Proper storage when not in use.

5. Environmental Conditions

Extreme heat or freezing temperatures can damage batteries.

Sump Pump Battery Backup: What You Need To Know

When the power goes out during a heavy rainstorm or flash flood, your sump pump is your first line of defense against a flooded basement. But without power, that pump is useless—unless you have a sump pump battery backup.

Batteries Store offer high-performance sump pump batteries designed to protect your home from water damage when it matters most.

What Is a Sump Pump Battery Backup?

A sump pump battery backup is a secondary power system that automatically kicks in when your primary sump pump loses power—typically during outages caused by severe weather. It ensures your sump pump keeps running and draining excess water from your basement, crawl space, or foundation.

These battery systems are essential for Canadian homes, especially in areas like Calgary, where spring melts, heavy rains, and flood warnings are not uncommon.

Why Do You Need a Battery Backup for Your Sump Pump?

Here’s why a sump pump battery backup isn't just a luxury—it’s a necessity:

1. Protection During Power Outages

Most sump pumps are electric, meaning they stop working during outages. A battery backup ensures uninterrupted operation when you need it most.

2. Flood Prevention

Even a few inches of water can lead to costly structural damage, mold growth, and ruined belongings. A backup keeps your basement dry and safe.
